Smooth Dial or Ten Notches

A payout terminal offers two modes, and you must pick one before pressing the button. Mode A pays a dollar amount drawn uniformly from the continuous interval $[0, 10]$. Mode B pays a whole-dollar amount drawn uniformly from the integers $\{0, 1, 2, \dots, 10\}$. Is one mode better than the other? Which would you pick, and why?
